Android - Drain battery quickly on purpose

Question

I am nearly finished with my app and last functionality to be made is to call specific action when battery level reaches below specific level.

So for test purposes I am wondering - how can I drain battery?

P.S - Using AVD wont work since my app is using Google Play services so I am testing app on my phone.

Answer 1

For fastest drain turn on at once all battery drainers:

• Acquire a Wake lock with Full screen brightness (No. 1 battery drainer)
• Vibration
• GPS with zero time polling intervals
• Turn on WiFi and continuously issue http requests
• Turn on Bluetooth and continuously issue scan commands

And, since you're a smart guy, you will probably use this app instead of hand-coding all of the above.

Answer 2

There is an AVD target that contains Play Services (Google APIs target).

Edit: you should also be able to use Genymotion from what I've read. It's also much faster than the stock emulator, but if your app uses any native code it may not work.
